Wike said the police has refused to make public the communication an APC chieftain and a former commissioner had with Alkali's killers.
Wike stated this on Thursday, January 5, when he hosted the management of the Independent Newspapers Limited at the Government House in Port Harcourt.
He accused the police of withholding the communication a chieftain of the All Progressives Congress (APC) and a former commissioner had with the killers before the DSP was murdered.
Wike said: "The police should let the world know where the DSP was killed. What is the polling unit where he was killed? The former Commissioner of Power, who was mentioned by the killers, has he been questioned?
"Where is the call log of that former commissioner as communicated with the killers? Have they checked the discussions between the former commissioner and the arrested killers?
"They know the truth but they want to cover a lot of things. The Army announced that they recovered the uniforms from the forest. Was there a polling unit in the forest?"
